What is TRANSIMS?
The TRansportation ANalysis and SIMulation System (TRANSIMS) is one project in the multi-track Travel Model Improvement Program sponsored by the U.S. Department of Transportation and the Environmental Protection Agency. The TRANSIMS project is a major effort to develop new, integrated transportation and air quality forecasting procedures to satisfy the Intermodal Surface Transportation Efficiency Act and the Clean Air Act and its amendments. Development of TRANSIMS is being led by the Los Alamos National Laboratory (LANL). TRANSIMS is a set of integrated analytical and simulation models and supporting data bases. The TRANSIMS methods deal with individual behavioral units and predicts trips for individual households, residents and vehicles rather than for zonal aggregations of households. TRANSIMS also predicts the movement of individual loads of freight. A regional microsimulation executes the generated trips on the transportation network and predicts the performance of individual vehi
